The

guarantees the right to "keep and bear arms". Concealed weapons bans were passed in Kentucky and Louisiana in 1813. (In those days open carry of weapons for self-defense was considered acceptable; concealed carry was denounced as the practice of criminals.) By 1859, Indiana, Tennessee, Virginia, Alabama, and Ohio had followed suit. By the end of the nineteenth century, similar laws were passed in places such as Texas, Florida, and Oklahoma, which protected some gun rights in their state constitutions. Before the mid-1900s, most U.S. states had passed concealed carry laws rather than banning weapons completely. Until the late 1990s, many Southern states were either "No-Issue" or "Restrictive May-Issue". Since then, these states have largely enacted "Shall-Issue" licensing laws, with numerous states legalizing " Unrestricted concealed carry" and the remaining "May-issue" licensing laws being abolished in 2022 by the U.S. Supreme Court.

Most states in this category allow any non-prohibited person to carry regardless of state of residency, with the sole exception of North Dakota. * Permit requirement jursdiction: one in which a permit is required to carry a concealed handgun. Historically, some states were considered "may-issue" jurisdictions where an applicant was required to provide a proper cause or need to be issued a permit to carry a concealed weapon. On June 23, 2022, these laws were found unconstitutional by the

Some states that allow permitless concealed carry and still issue concealed carry permits may impose restrictions on concealed carry for certain places and/or at certain times (e.g., special events, large public gatherings, etc.). In some such situations, those holding a valid concealed carry permit may be exempt from such restrictions.


Permit requirement jurisdictions

A permit requirement jurisdiction is one in which a government-issued permit is required to carry a concealed handgun in public. Before the U.S. Supreme Court ruling in ''New York State Rifle & Pistol Association, Inc. v. Bruen'', these jurisdictions were further split between "shall-issue", which is the current national licensing standard where the granting of licenses is subject only to meeting determinate criteria laid out in the law, and "may-issue" where the granting of such licenses was at the discretion of local authorities. Since the abolishment of "may-issue" permitting the U.S. Supreme Court has stated it is still legal for U.S. jurisdictions subject to the Constitution to require a permit to carry a concealed handgun, and that background checks, training, and proper fees can be required without violating the

Concealed carry on U.S. military installations

While members of the Armed Services may receive extensive small arms training,

. Military installations do not recognize state-issued concealed carry permits, and state firearms laws generally do not apply to military bases, regardless of the state in which the installation is located. Federal law (18 USC, Section 930) generally forbids the possession, transport, and carrying of firearms on military installations without approval from the installation commander. Federal law gives installation commanders wide discretion in establishing firearms policies for their respective installations. In practice, local discretion is often constrained by policies and directives from the headquarters of each military branch and major commands. Installation policies can vary from no-issue for most bases to shall-issue in rare circumstances. Installations that do allow the carrying of firearms typically restrict carrying to designated areas and for specific purposes (i.e., hunting or officially sanctioned shooting competitions in approved locations on the installation). Installation commanders may require the applicant complete extensive firearms safety training, undergo a mental health evaluation, and obtain a letter of recommendation from their unit commander (or employer) before such authorization is granted. Personnel that reside on a military installation are typically required to store their personally-owned firearms in the installation armory, although the installation commander or provost marshal may permit a service member to store their personal firearms in their on-base dwelling if they have a

Concealed carry on Native American Reservations

Concealed carry policies on Native American reservations are covered by the tribal laws for each reservation, which vary widely from "No-Issue" to "Shall-Issue" and "Unrestricted" either in law or in practice. Some Native American tribes recognize concealed carry permits for the state(s) in which the reservation is located, while others do not. For reservations that do not recognize state-issued concealed carry permits, some completely ban concealed carry, while others offer a tribal permit for concealed carry issued by the tribal police or tribal council. Tribal concealed carry permits may be available to the general populace or limited to tribal members, depending on tribal policies. Tribal law typically pre-empts state law on the reservation. The only exception is while traversing the reservation on a state-owned highway (including interstate, U.S. routes, and in some instances county roads), in which case state law and the federal Firearm Owners' Protection Act (FOPA) apply.


Limitations on concealed carry

Prohibitions of the concealed carry of firearms and other weapons by local governments predate the establishment of the United States. In 1686, New Jersey law stated “no person or persons … shall presume privately to wear any pocket pistol … or other unusual or unlawful weapons within this Province.” After the federal government was established, states and localities continued to restrict people from carrying hidden weapons. Tennessee law prohibited this as early as 1821. By 1837, Georgia passed into effect “An Act to guard and protect the citizens of this State, against the unwarrantable and too prevalent use of deadly weapons.” Two years later, Alabama followed suit with “An Act to Suppress the Evil Practice of Carrying Weapons Secretly.” Delaware prohibited the practice in 1852. Ohio did the same in 1859, a policy that remained in effect until 1974. Cities also regulated weapons within their boundaries. In 1881,

Training requirements

Some states require concealed carry applicants to certify their proficiency with a firearm through some type of training or instruction. Certain training courses developed by the

mechanics and terminology, cleaning and maintenance of a firearm, concealed carry legislation and limitations, liability issues, carry methods and safety, home defense, methods for managing and defusing confrontational situations, and practice of gun handling techniques without firing the weapon. Most required CCW training courses devote a considerable amount of time to liability issues. Depending on the state, a practical component during which the attendee shoots the weapon for the purpose of demonstrating safety and proficiency, may be required. During range instruction, applicants would typically learn and demonstrate safe handling and operation of a firearm and accurate shooting from common self-defense distances. Some states require a certain proficiency to receive a passing grade, whereas other states (e.g., Florida) technically require only a single-shot be fired to demonstrate handgun handling proficiency. CCW training courses are typically completed in a single day and are good for a set period, the exact duration varying by state. Some states require re-training, sometimes in a shorter, simpler format, for each renewal. A few states, e.g., South Carolina, recognize the safety and use-of-force training given to military personnel as acceptable in lieu of formal civilian training certification. Such states will ask for a military ID (South Carolina) for active persons or

permitting qualified active and retired law enforcement officers to carry concealed weapons in the United States. Virginia recognizes eight specific training options to prove competency in handgun handling, ranging from DD214 for honorably discharged military veterans, to certification from law enforcement training, to firearms training conducted by a state or NRA certified firearms instructor including electronic, video, or on-line courses. While any one of the eight listed options will be considered adequate proof, individual circuit courts may recognize other training options. A small number of states, such as Alabama and Georgia, have no training requirements to obtain a permit—only a requirement that the applicant successfully pass the required background check before issuance.


Reciprocity

Many jurisdictions recognize (honor) a permit or license issued by other jurisdictions. Recognition may be granted to all jurisdictions or some subset which meets a set of permit-issuing criteria, such as training comparable to the honoring jurisdiction or certain background checks. Several states have entered into formal agreements to mutually recognize permits. This arrangement is commonly called reciprocity or mutual recognition. A few states do not recognize permits issued by any other jurisdiction, but offer non-resident permits for out-of-state individuals (who possess a valid concealed carry permit from their home state) who wish to carry while visiting such states. There are also states that neither recognize out-of-state concealed carry permits nor issue permits to non-residents, resulting in a complete ban on concealed carry by non-residents in such states. There are also states (Illinois and Rhode Island) that do not recognize out-of-state permits for carry on-foot, but do permit individuals with out-of-state concealed carry permits to carry while traveling in their vehicle (normally in accordance with the rules of the state of issuance). Recognition and reciprocity of concealed carry privileges varies. Some states (e.g. Indiana, Virginia, Ohio) unilaterally recognize all permits. Others such as Michigan, limit such universal recognition to residents of the permit-issuing state. While 37 states have reciprocity agreements with at least one other state and several states honor all out-of-state concealed carry permits, some states have special requirements like training courses or safety exams, and therefore do not honor permits from states that do not have such requirements for issue. Some states make exceptions for persons under the minimum age (usually 21) if they are active or honorably-discharged members of the military or a police force (the second of these two is subject additionally to
federal law Federal law is the body of law created by the federal government of a country. A federal government is formed when a group of political units, such as states or provinces join in a federation, delegating their individual sovereignty and many po ...
). States that do not have this exemption generally do not recognize any license from states that do. An example of this is the state of Washington's refusal to honor any Texas LTC as Texas has the military exception to age. Idaho, Mississippi, North Dakota, South Dakota, and Tennessee have standard and enhanced permits that have different requirements to obtain and also have unique reciprocity with different states; Utah and West Virginia have provisional permits for 18-20 year olds with more limited recognition by other states. Permits from Idaho (enhanced), Kansas, Michigan, and North Dakota (class 1) have the highest number of recognition by other states (39 states). One can obtain multiple state permits in an effort to increase the number of states where that user can carry a legally concealed weapon. It is common practice to use a CCW Reciprocity Map to gain clarity on which states will honor the person's combination of resident and non-resident permits given the variety of standards and legal policies from state to state. There are also various mobile applications that guide users in researching state concealed carry permit reciprocity. Although carry may be legal under State law in accordance with reciprocity agreements, the Federal Gun Free School Zones Act subjects an out-of-state permit holder to federal felony prosecution if they carry a firearm within 1000 feet of any K–12 school's property line; however, the enforcement of this statute is rare given several states' nullification statutes prohibiting state law enforcement officers from enforcing federal firearms laws. However, states may have their own similar statutes that such officers will enforce, and potentially expose the carrier to later prosecution under the Act.


Restricted premises

While generally a concealed carry permit allows the permit holder to carry a concealed weapon in public, a state may restrict carry of a firearm including a permitted concealed weapon while in or on certain properties, facilities or types of businesses that are otherwise open to the public. These areas vary by state (except for the first item below; federal offices are subject to superseding federal law) and can include: * Federal government facilities, including post offices, IRS offices, federal court buildings, military/VA facilities and/or correctional facilities, Amtrak trains and facilities, and Corps of Engineers-controlled property (carry in these places is prohibited by federal law and preempts any existing state law). Carry on land controlled by the Bureau of Land Management (federal parks and wildlife preserves) is allowed by federal law as of the 2009 CARD Act, but is still subject to state law. However, carry into restrooms or any other buildings or structures located within federal parks is illegal in the United States, despite concealed carry being otherwise legal in federal parks with a permit recognized by the state in which the federal park is located. Similarly, concealed carry into caves located within federal parks is illegal. * State and local government facilities, including courthouses, DMV/DoT offices, police stations, correctional facilities, and/or meeting places of government entities (exceptions may be made for certain persons working in these facilities such as judges, lawyers, and certain government officials both elected and appointed) * Venues for political events, including rallies, parades, debates, and/or polling places * Educational institutions including elementary/secondary schools and colleges. Some states have "drop-off exceptions" which only prohibit carry inside school buildings, or permit carry while inside a personal vehicle on school property.

laws vary by state. * Public interscholastic and/or professional sporting events and/or venues (sometimes only during a time window surrounding such an event) * Amusement parks, fairs, parades and/or carnivals * Businesses that sell alcohol (sometimes only "by-the-drink" sellers like restaurants, sometimes only establishments defined as a "bar" or "nightclub", or establishments where the percentage of total sales from alcoholic beverages exceeds a specified threshold) * Hospitals (even if hospitals themselves are not restricted, "teaching hospitals" partnered with a medical school are sometimes considered "educational institutions"; exceptions are sometimes made for medical professionals working in these facilities) * Churches, mosques and other "Houses of worship", usually at the discretion of the church clergy (Ohio allows with specific permission of house of worship) * Municipal mass transit vehicles or facilities * Sterile areas of airports (sections of the airport located beyond security screening checkpoints, unless explicitly authorized) * Non-government facilities with heightened security measures (Nuclear facilities, power plants, dams, oil and gas production facilities, banks, factories, unless explicitly authorized) * Aboard aircraft or ships unless specifically authorized by the pilot in command or ship captain * Private property where the lawful owner or lessee has posted a sign or verbally stated that firearms are not permitted * Any public place, while under the influence of alcohol or drugs (including certain prescription or over-the-counter medications, depending on jurisdiction)


"Opt-out" statutes ("gun-free zones")

Some states allow private businesses to post a specific sign prohibiting concealed carry within their premises. The exact language and format of such a sign varies by state. By posting the signs, businesses create areas where it is illegal to carry a concealed handgun—similar to regulations concerning schools, hospitals, and public gatherings. Violation of such a sign, in some of these states, is grounds for revocation of the offender's concealed carry permit and criminal prosecution. Other states, such as Virginia, enforce only trespassing laws when a person violates a "Gun Free Zone" sign. In some jurisdictions trespass by a person carrying a firearm may have more severe penalties than "simple" trespass, while in other jurisdictions, penalties are lower than for trespass. Such states include: Arizona, Arkansas, Connecticut, Illinois, Kansas, Louisiana, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Mexico, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and Wisconsin. There is considerable dispute over the effectiveness of such "

'' laws banning gun-related practices, only law-abiding individuals will heed the signage and disarm. Individuals or groups intent on committing far more serious crimes, such as armed robbery or murder, will not be deterred by signage prohibiting weapons. Further, the reasoning follows that those wishing to commit mass murder might ''intentionally'' choose gun-free venues like shopping malls, schools and churches (where weapons carry is generally prohibited by statute or signage) because the population inside is disarmed and thus less able to stop them. In some states, business owners have been documented posting signs that appear to prohibit guns, but legally do not because the signs do not meet local or state laws defining required appearance, placement, or wording of signage. Such signage can be posted out of ignorance to the law, or intent to pacify gun control advocates while not actually prohibiting the practice. The force of law behind a non-compliant sign varies based on state statutes and case law. Some states interpret their statutes' high level of specification of signage as evidence that the signage must meet the specification exactly, and any quantifiable deviation from the statute makes the sign non-binding. Other states have decided in case law that if efforts were made in good faith to conform to the statutes, the sign carries the force of law even if it fails to meet current specification. Still others have such lax descriptions of what is a valid sign that virtually any sign that can be interpreted as "no guns allowed" is binding on the license holder. Note that virtually all jurisdictions allow some form of oral communication by the lawful owner or controller of the property that a person is not welcome and should leave. This notice can be given to anyone for any reason (except for statuses that are protected by the Federal

Brandishing and printing

Printing refers to a circumstance where the shape or outline of a firearm is visible through a garment while the gun is still fully covered, and is generally not desired when carrying a concealed weapon. Brandishing can refer to different actions depending on jurisdiction. These actions can include printing through a garment, pulling back clothing to expose a gun, or unholstering a gun and exhibiting it in the hand. The intent to intimidate or threaten someone may or may not be required legally for it to be considered brandishing. Brandishing is a crime in most jurisdictions, but the definition of brandishing varies widely. Under California law, the following conditions have to be present to prove brandishing: In Virginia law:

Federal Gun Free School Zones Act

The Federal Gun Free School Zone Act limits where a person may legally carry a firearm. It does this by making it generally unlawful for an armed citizen to be within 1,000 feet (extending out from the property lines) of a place that the individual knows, or has reasonable cause to believe, is a K–12 school. Although a state-issued carry permit may exempt a person from this restriction in the state that physically issued their permit, it does not exempt them in other states which recognize their permit under reciprocity agreements made with the issuing state.

from enacting or enforcing any regulations that restrict possession of firearms in National Parks or Wildlife Refuges, as long as the person complies with laws of the state in which the unit is found. This provision was supported by the National Rifle Association and opposed by the Brady Campaign to Prevent Gun Violence, the National Parks Conservation Association, and the Coalition of National Park Service Retirees, among other organizations. As of February 2010 concealed handguns are for the first time legal in all but 3 of the nation's 391 national parks and wildlife refuges so long as all applicable federal, state, and local regulations are adhered to. Hawaii is a notable exception. Concealed and open carry are both illegal in Hawaii for all except retired military or law enforcement personnel. Previously firearms were allowed into parks if cased and unloaded.

Opponents of national reciprocity have pointed out that this legislation would effectively require states with more restrictive standards of permit issuance (e.g., training courses, safety exams, "good cause" requirements, et al.) to honor permits from states with more liberal issuance policies. Supporters have pointed out that the same situation already occurs with marriage certificates, adoption decrees and other state documents under the "full faith and credit" clause of the U.S. Constitution. Some states have already adopted a "full faith and credit" policy treating out-of-state carry permits the same as out-of-state driver's license or marriage certificates without federal legislation mandating such a policy.

'', effectively extending the Heller decision to states and local governments nationwide. Banning handguns in any jurisdiction has the effect of rendering invalid any licensed individual's right to carry concealed in that area except for federally exempted retired and current law enforcement officers and other government employees acting in the discharge of their official duties. In 2022, the Supreme Court ruled in '' New York State Rifle & Pistol Association, Inc. v. Bruen'', that the Second Amendment does protect "an individual's right to carry a handgun for self-defense outside the home." The case struck down New York's strict law requiring people to show "proper cause" in order to get a concealed weapons permit, and could affect similar laws in other states such as California, Hawaii, Maryland, Massachusetts, New Jersey, and Rhode Island. Shortly after the Supreme Court ruling, the attorney generals of each of California, Hawaii (concealed carry licenses only), Maryland, Massachusetts, New Jersey, and Rhode Island (permits issued by municipalities only) issued guidance that their "proper cause" or similar requirements would no longer be enforced.


Legal liability

Even when self-defense is justified, there can be serious civil or criminal liabilities related to self-defense when a concealed carry permit holder brandishes or fires their weapon. For example, if innocent bystanders are hurt or killed, there could be both civil and criminal liabilities even if the use of deadly force was completely justified. Some states technically allow an assailant who is shot by a gun owner to bring civil action. In some states, liability is present when a resident brandishes the weapon, threatens use, or exacerbates a volatile situation, or when the resident is carrying while intoxicated. It is important to note that simply pointing a firearm at any person constitutes felony assault with a deadly weapon unless circumstances validate a demonstration of force. A majority of states who allow concealed carry, however, forbid suits being brought in such cases, either by barring lawsuits for damages resulting from a criminal act on the part of the plaintiff, or by granting the gun owner immunity from such a civil suit if it is found that they were justified in shooting. Simultaneously, increased passage of "

" laws allow persons who own firearms and/or carry them concealed to use them without first attempting to retreat. The "Castle Doctrine" typically applies to situations within the confines of one's own home. Nevertheless, many states have adopted escalation of force laws along with provisions for concealed carry. These include the necessity to first verbally warn a trespasser or lay hands on a trespasser before a shooting is justified (unless the trespasser is armed or assumed to be so). This escalation of force does not apply if the shooter reasonably believes a violent felony has been or is about to be committed on the property by the trespasser. Additionally some states have a
duty to retreat In law, the duty to retreat, or requirement of safe retreat,''Criminal Law - Cases and Materials'', 7th ed. 2012, Wolters Kluwer Law & Business; John Kaplan, Robert Weisberg, Guyora Binder, /ref> is a legal requirement in some jurisdictions t ...
provision which requires a permit holder, especially in public places, to vacate themself from a potentially dangerous situation before resorting to deadly force. The duty to retreat does not restrictively apply in a person's home or business though escalation of force may be required. In 1895 the Supreme Court ruled in '' Beard v. United States'' that if an individual does not provoke an assault and is residing in a place they have a right to be, then they may use considerable force against someone they reasonably believe may do them serious harm without being charged with murder or manslaughter should that person be killed. Further, in Texas and California homicide is justifiable solely in defense of property. In other states, lethal force is authorized only when serious harm is presumed to be imminent. Even given these relaxed restrictions on use of force, using a handgun must still be a last resort in some jurisdictions; meaning the user must reasonably believe that nothing short of deadly force will protect the life or property at stake in a situation. Additionally, civil liabilities for errors that cause harm to others still exist, although civil immunity is provided in the Castle Doctrine laws of some states (e.g., Texas).

Quinnipiac University economist Mark Gius summarized literature published between 1993 and 2005, and found that ten papers suggested that permissive CCW laws reduce crime, one paper suggested they increase crime, and nine papers showed no definitive results. A 2017 review of the existing literature concluded, "Given the most recent evidence, we conclude with considerable confidence that deregulation of gun carrying over the last four decades has undermined public safety—which is to say that restricting concealed carry is one gun regulation that appears to be effective."

Firearms permit holders in active shooter incidents

In 2016 FBI analyzed 40 "active shooter incidents" in 2014 and 2015 where bystanders were put in peril in on-going incidents that could be affected by police or citizen response. Six incidents were successfully ended when citizens intervened. In two stops citizens restrained the shooters, one unarmed, one with pepper spray. In two stops at schools, the shooters were confronted by teachers: one shooter disarmed, one committed suicide. In two stops citizens with firearms permits exchanged gunfire with the shooter. In a failed stop attempt, a citizen with a firearms permit was killed by the shooter. In 2018 the FBI analyzed 50 active shooter incidents in 2016 and 2017. This report focused on policies to neutralize active shooters to save lives. In 10 incidents citizens confronted an active shooter. In eight incidents the citizens stopped the shooter. Four stops involved unarmed citizens who confronted and restrained or blocked the shooter or talked the shooter into surrender. Four stops involved citizens with firearms permits: two exchanged gunfire with a shooter and two detained the shooter at gunpoint for arrest by responding police. Of the two failed stops, one involved a permit holder who exchanged gunfire with the shooter but the shooter fled and continued shooting and the other involved a permit holder who was wounded by the shooter. "Armed and unarmed citizens engaged the shooter in 10 incidents. They safely and successfully ended the shootings in eight of those incidents. Their selfless actions likely saved many lives.""Active Shooter Incidents in the United States in 2016 and 2017", Federal Bureau of Investigation, April 2018.
"The FBI defines an active shooter as one or more individuals actively engaged in killing or attempting to kill people in a populated area. ... The active aspect of the definition inherently implies that both law enforcement personnel and citizens have the potential to affect the outcome of the event based upon their responses to the situation."
